Neither meditation is said to be sufficient for enlightenment, at least to Buddhists who are not Zen (or Ch'an) practitioners.

We cannot just ask Siddhartha Gautama anymore about the practices and his words were mysticized and changed over generations, as were ethical rules and especially the added monastic rules.

Even Pali Canon is suspect in pieces and that's a more reliable source in the practices he reformed.
